Both unfold to a 7.6″ landscape screen, and for widescreen video they are a draw: 16:9 plays at about 7.1″ on the Duo and 7.0″ on the Z Fold 8. The difference shows with squarer content. The Fold 8’s panel is almost exactly 4:3, so iPad-style apps, 4:3 video and square posts come out about 8% larger by area than on the Duo.
